Hello
One of the most common problems with error code 0x204 is an instance of Remote Desktop Protocol not enabled on your Windows computer. In this case, you can manually enable it through the System Properties screen and allow network-level connections to resolve the issue.
However, this could also be caused by your firewall (since the process used by Remote Desktop is exploited by many malware). In order to fix this, in this case, you need to establish exclusion rules, disable real-time protection, or completely uninstall third-party security suites.
